OBJECTIVES
The main objective was to assess the influence of resistance exercise on pain threshold and pain ratings. Secondary objectives included measuring state anxiety, body awareness, systolic blood pressure, diastolic blood pressure, and heart rate responses.
METHODS
Pressure (3 kg force) was applied to the middle digit of the left hand for two minutes using a Forgione-Barber pain stimulator before and after (five minute and 15 minutes) resistance exercise and quiet rest. Resistance exercise consisted of 45 minutes of lifting three sets of 10 repetitions at 75% of an individual's one repetition maximum. Quiet rest consisted of sitting quietly in a room free from distractions.
RESULTS
Data were analysed by repeated measures analysis of variance for multifactor experiments. Pain threshold was significantly higher (p<0.05) and pain ratings were significantly lower (p<0.05) five minutes after resistance exercise. Changes in pain perception were accompanied by changes in heart rate, systolic blood pressure, and body awareness after exercise.
CONCLUSION
A single bout of resistance exercise is capable of modifying the sensation of experimentally induced pain.
目的
主要目的是评估抗阻运动对疼痛阈值和疼痛评分的影响。次要目的包括测量状态焦虑、身体感知、收缩压、舒张压和心率反应。
方法
在抗阻运动和安静休息前（五分钟）和后（五分钟和十五分钟），使用福吉奥内 - 巴伯疼痛刺激器对左手的中指施加压力（3千克力）两分钟。抗阻运动包括以个人一次重复最大值的75%进行三组每组10次重复的举重，持续45分钟。安静休息包括在无干扰的房间里安静地坐着。
结果
通过多因素实验的重复测量方差分析对数据进行分析。抗阻运动五分钟后，疼痛阈值显著升高（p<0.05），疼痛评分显著降低（p<0.05）。运动后疼痛感知的变化伴随着心率、收缩压和身体感知的变化。
结论
单次抗阻运动能够改变实验诱导疼痛的感觉。
